Question

the mean of a given distribution is 50. If sigma fixi = 5160 + 30p and sigma fi = 92+ p , then what is the value of p.​

Answer 1

Answer:

p= 23

Step-by-step explanation:

Mean = sigma fixi/sigma fi

$50 = \frac{5160 + 30p}{92 + p} \\ 4600 + 50p = 5160 + 30p \\ 50p - 30p = 5160 - 4600 \\ 20p = 560 \\ p = 23$
